In the Christian Science textbook, Science and Health with Key to the Scriptures, Mary Baker Eddy explains the scientific laws behind the teachings and healings of Christ Jesus. From the first chapter, “Prayer,” to her exegesis of Genesis and Revelation, to a Glossary of biblical terms, the author invites readers to deeply consider the allness of God, the perfection of man as God's spiritual creation, and how an understanding of these facts can free one from sin, disease, and death—just as they did in biblical times.
